When the temperature decreases further below the dewpoint, there is a change of state and water will deposit on the surfaces in the form of drops and droplets. When the air is unsaturated (< RH), the temperature at dewpoint is lower than the air temperature, whereas when the air gets saturated ( RH), these two value coincide.
